Filed:

Aug 18, 2011

Appl. No.:

13/213080

Inventors:

Min Chul Kim - Santa Clara CA, US
Paul Yuan - San Jose CA, US

Assignee:

Apple Inc. - Cupertino CA

International Classification:

H01R 13/64

US Classification:

439680

Abstract:

Circuits, methods, and apparatus that may provide protection from exposed wires or terminals when a power plug is damaged or destroyed. One example may provide a plug having an inner cover that shields power carrying wires or terminals when an outer shell is damaged or destroyed. The inner cover may include openings to receive conductors, where the openings may lead to terminals or wires that connect to plug prongs. The received conductors may attach directly or indirectly to an outer shell, and further to a power cord, circuitry, or other electronic components. When the outer shell is damaged or destroyed, the conductors may pull out of the openings in the inner cover, thus disconnecting from the wires or terminals. The wires or terminals may thus remain protected by the inner shell, avoiding exposure to contact by users or inadvertent conductors.

International Classification:

H01R 43/02

US Classification:

29861, 29857, 29860, 43960741

Abstract:

High speed connector inserts and cables having improved heat conduction, high strength, and may be manufactured in a reliable manner. One example may provide a connector insert having several paths by which heat may be removed from circuitry in the cable insert. In one example, heat may be removed from one or more circuits by forming a thermal path between a circuit and a shield of the connector insert. Another path may include one or more pads on a side of an integrated circuit board that are soldered directly to the shield. A braiding surrounding a cable may be soldered or otherwise thermally connected to the shield. Another example may provide a cable having a braiding that includes one or more types of fibers, such as aramid fibers. Another example may provide for increased manufacturability by using a wire comb and a solder bar.

Inventors:

Paul Yuan - San Jose CA, US
Min Chul Kim - Santa Clara CA, US

Assignee:

Apple Inc. - Cupertino CA

International Classification:

H01R 9/05

US Classification:

439581

Abstract:

Structures and methods that simplify the assembly of connector inserts. One example may provide a connector insert having a termination block that is arranged to receive an end of a cable. The termination block may provide a first number of conductors in a first row and a second number of conductors in a second row. The termination block may be stepped such that the first number of conductors emerge from the termination block at a different position along their lengths than the second number of conductors. The first number of conductors may then attach to a first side of a printed circuit board or other connector portion, while the second number of conductors may then attach to a second side of the printed circuit board or other connector portion.
